Have an old LH Sav 110 from the early 60's with the counter-bored breech bolt/barrel that I'd like to convert to the later flat bolt/breech system. Looks like I can get all the LH bolt-head parts easy enough. Problem arises with the bolt. This was what they called a "short action", but really has a medium length bolt body. This is no longer available and won't work anyway because the pin holes for the bolt body are machined horizontal instead of vertical. My solution is to get a long-action bolt body,(this is available from Numrich) shorten it to the length of my current bolt body and re-drill the holes properly for the new bolt head. I think this is do-able. The real problem comes with the firing pin. It's gonna be too long because of the extra length of the bolt nose that went into the barrel counter-bore. Anyone know if I can shorten the end of the firing pin to accomodate the new set-up? Or should I just can the idea? What to do, what to do. This gun has a lot of sentimental value, being my first centerfire hunting rifle. I'd like to be able to change barrels and can't do it as is. It's gonna be a 358 Win first, if I can! Right now it's a 243 Win. Would appreciate any input. Thanks.
